Surface Complex Formation Data:

Mineral: Goethite
Reference: SHV08
SCM Type: CDM - (CD-)MUSIC
Ligand: Ca<2+> - calcium
Site Type: »Fe-singly
Equation: »Fe-OH<0.5-> + Ca<2+> + H2O  ⇔  »Fe-OH<0.18->Ca(OH)<0.68+> + H<1+>
LogK: -9.17 ± 0.09         LogK2.31 nm−2 (SSD-normalized):   -9.10
Experiment: Potentiometric Titration
Ionic Strength: NaNO3
Temperature: 298.15 K
